The planning committee has reviewed his presentation noting no manufacture bias. His participation in today s event should not be construed to imply endorsement of 3M products from Heartland National TB Center, The University of Texas Health Science Center at Tyler, or the Centers for Disease Control and Prevention. 1

2 Respirator Training Barry Sanders Senior Territory Manager 3M Personal Safety Division Regulatory Organizations OSHA - Occupational Safety & Health Administration Enforces regulation 29 CFR Where respirators are in use in the work place, a formal respiratory protection program must be established covering basic requirements outlined in the standard. NIOSH - National Institute for Occupational Health & Safety (CDC) The federal agency responsible for conducting research and making recommendations for the prevention of work-related injury and illness. Tests & approves respirators for use in the work place ACGIH - American Conference of Industrial Hygienists Creates TLV s investigates, recommends, and annually reviewing exposure limits for chemical substances. 2

3 Elements of a Respirator Program Exposure Assessment Written Respiratory Program Respirator Selection Medical Evaluation Fit Testing Respirator Training Record Keeping Exposure assessment (Duty to Warn) 1. Material safety data sheets for the chemicals in the workplace should be used to provide information on the health effects and hazards for those materials. 2. Instruction must be performed on the respiratory hazards to which the workers are potentially exposed during routine and emergency situations. 3. The training on hazardous chemicals required by the Hazard Communication standard, 29 CFR , meets this requirement. 4. However, if the respiratory hazard is exempt from the Hazard Communication rule (e.g., biological and radioactive hazards), training on these hazards must be completed. 5. Annual training on the respiratory hazards is required. 6. The employees should be told why the respirator is necessary. 3

4 Respirator Program & Training 1. Maintain a written respiratory protection program with worksite specific procedures for fit testing and training. 2. Provide instruction on the respiratory hazards to which the workers are potentially exposed during routine and emergency situations. 3. Provide instruction on the uses and limitations of all respirators worn in the work area including a change out program. 4. Instruct and demonstrate to employees how to properly don and adjust any respirators worn according to the manufacturers instructions. 5. Allow the employees an opportunity to practice these procedures. 6. Provide user seal check instructions. 7. Fit test each employee to be assigned a respirator and size. 8. Instruct the employees in the procedures for the maintenance and storage of the respirators being used. 9. Inform the employees how to recognize medical signs and symptoms that may limit or prevent the effective use of the respirators. 10. Document the successful completion of training and fit testing for all employees wearing respirators. 2 Way Street Right to Know Employees have the right to question, investigate and take appropriate measures to ensure safe health practices. Employers shall provide data upon request to show duediligence has been done in the assessment, selection and change out procedure of respirators. Proper and well maintained equipment must be made available to the employees. Material Data sheets should also be made available for hazards present in the work place. 4

5 Instruction for Use and Limitations of Respirators All respirators, filters and chemical cartridges have use limitations. There is not one all-purpose respirator. Employees will be trained on the respirators selected by the employer for the specific work environment. Review the use and limitations of the respirator - read the respirator instructions that come with each respirator package. The NIOSH approval label also provides some of this information. The effect of improper respirator fit, usage or maintenance will be explained. For respirators other than SCBA or combination airline respirator/scba, the employee will exit the contaminated area in all respirator emergency situations, including respirator malfunction. Donning, Doffing & Storage Always inspect your respirator prior to donning. A respirator must be put on and worn properly if it is to fit and offer effective protection. Donning & Doffing instructions should be fully explained and demonstrated to the wearer. Respirator if not in use or on the person must be stored in a proper container. Never leave a respirator out in the open or on a hook without being in a proper container. 5

6 User Seal Check or Positive & Negative Pressure check At this point, all employees should be wearing a respirator. Instruct the employees on how to conduct a user seal check. A user seal check is a method of determining if the respirator has been put on properly and has been fitted properly. A user seal check must be conducted each time the respirator is put on. Refer to user seal check procedures on each respirator package. When the employees have completed the user seal check procedure, the instructor should ask, Does anyone feel any leakage around the seal of the respirator? If so, the wearer should review donning instructions, make adjustments to the fit, and perform the user seal check again. If a proper fit cannot be accomplished, the wearer must select another respirator and repeat the user seal check procedure. Respirator Maintenance Employees who will be responsible for the maintenance of their own respirators must be instructed in the applicable cleaning, inspection, repair, and storage procedures. Disposable respirators may simply be thrown away. In service date should be labeled on cartridges In some cases chemical cartridges should be stored separate from face piece if crosscontamination could occur. 6

7 Medical Signs and Symptoms The medical signs and symptoms that may limit or prevent effective use of the respirator, listed on the medical questionnaire of Appendix C, must be explained. A pre medical written questionnaire must be completed and reviewed by a certified professional to determine adequate physical capacity to wear a respirator. A Pulmonary Function Test may be performed by individuals who s physical condition may be of concern. Individuals that cannot pass a PFT should not wear a respirator. Training Documentation OSHA requires that employers keep written documentation of all employees that are fit tested. Employees to acknowledge pass of fit test by signature on fit test form. Use a Respirator Training Attendance Roster that is signed by the employees and were trained on general use, limitations, change out and maintenance of respirators. If employees can demonstrate knowledge of the information conveyed in these steps, you will have conducted a respirator training session that meets existing OSHA requirements. 7

8 Fit Testing Fit Test Methods Qualitative and Quantitative Fit Tests Qualitative Fit Test Method (Agents) Scccharin, Bitrex, Isomyl acetate, Irritant smoke Persons that cannot detect agent must use an alternative agent or method Quantitative Fit test Method Use of a Portacount or Quantifit Persons unable to pass the fit test must select an alternate size, model or brand respirator and attempt again. Fit Test Procedure Each test exercise shall be performed for one minute. After each exercise the fit tester ask if the agent can be detected. If agent is present the wearer should discontinue test and inspect or re adjust, Test should resume from the beginning. The test subject shall be questioned by the test conductor regarding the comfort of the respirator upon completion of the protocol. If it has become unacceptable, an alternative size model or brand of respirator shall be tried. The respirator shall not be adjusted once the fit test exercises begin. Any adjustment voids the test, and the fit test must be repeated. 3M All Rights 8

9 Fit test Exercises (Qualitative) Normal Breathing - In a normal standing position, the subject shall breathe normally. Deep Breathing - In a normal standing position, the subject shall breathe slowly and deeply, taking caution so as not to hyperventilate. Turning Head Side to Side - Standing in place, the subject shall slowly turn his/her head from side to side between the extreme positions on each side. The head shall be held at each extreme momentarily so the subject can inhale at each side. Moving Head Up & Down - Standing in place, the subject shall slowly move his/her head up and down. The subject shall be instructed to inhale in the up position (i.e., when looking toward the ceiling). Talking Out Loud - The subject shall talk out loud slowly and loud enough so as to be heard clearly by the test conductor. The subject can read from a prepared text such as the Recite the Rainbow Passage Walking in place and move arms & head about Bending over - The test subject shall bend at the waist as if he/she were to touch his/her toes. Jogging in place shall be substituted for this exercise in those test environments such as shroud type QNFT or QLFT units that do not permit bending over at the waist.

Normal Breathing - Same as exercise #1 9

10 The Rainbow Passage When the sunlight strikes raindrops in the air, they act as a prism and form a rainbow. The rainbow is a division of white light into many beautiful colours. These take the shape of a long round arch, with its path high above, and its two ends apparently beyond the horizon. There is, according to legend, a boiling pot of gold at one end. People look, but no one ever finds it. When a man looks for something beyond his reach, his friends say he is looking for the pot of gold at the end of the rainbow.

13 Silicosis Silicosis is caused by exposure to respirable crystalline silica dust. Crystalline silica is a basic component of soil, sand, granite, and most other types of rock, and it is used as an abrasive blasting agent. Silicosis is a progressive, disabling, and often fatal lung disease. Cigarette smoking adds to the lung damage caused by silica. OSHA web site Silicosis 13

14 Use of Respirators OSHA 29 CFR (g)(1)(i)(A B) The employer shall not permit respirators with tightfitting face pieces to be worn by employees who have: facial hair that comes between the sealing surface of the face piece and the face or that interferes with valve function. or any (other) condition that interferes with the face toface piece seal or valve function. *3M Technical Data Bulletin # 165 Fit Testing Policy 14
